After school on Wednesday, the group took to the streets to protest with signs and bullhorns, marching from Benjamin Franklin High School to the site of the proposed incinerator.

There are several reasons for concern, including the incinerator's potential to burn up to 4,000 tons of waste each day.

According to the United Workers organization, the south Baltimore neighborhoods surrounding where the incinerator will be built already register some of the nation's highest levels of toxic air pollution. The group said the area already has some of the city's highest mortality rates for heart disease, lung cancer and chronic lower respiratory disease.

"Curtis Bay is a community just like any other, and it isn't fair that we have to breathe toxic air every day that hurts our health," said Destiny Watford, an 18-year-old community resident who is currently studying at Towson University. "This is why we are coming together -- to stop the incinerator and put an end to the cycle of failed development."

In the past few months, the Fair Development Campaign has launched a website and online petition against the plan, calling on Gov. Martin O'Malley to stop the construction.

The march was also endorsed by the Chesapeake Climate Action Network, Environmental Integrity Project, the Maryland Environmental Health Network, Clean Water Action, Community Research and the Global Alliance for Incinerator Alternatives.
